Figure 12.5<br />
One powerful way to inspect a waterfall is to enable its marker. Press the button.<br />
The display should change as in Fig.12.6. It is very easy to locate frequency zones where<br />
the decay 'suffers', like the peak around 2200Hz. After placing the cursor on it, it is<br />
possible to quickly move back and forth the calculated slices by means of the up and<br />
down keyboard arrows.<br />

Let's now change the CSD aspect. Go to the waterfall settings dialog and input 0.1ms<br />
Time Shift. After recalculating it you obtain the plot in Fig.12.7; as you now notice the<br />
slices are closer in time and decaying modes are more evident. Since the time span<br />
chosen for this waterfall was about 6.1ms the maximum allowed Time Shift you could<br />
input was around 0.2ms (considering 30 spectra as in this case).<br />

Let's now change the CSD aspect again. Go to the waterfall settings dialog and check<br />
the Reference box. After recalculating, you obtain the plot in Fig.12.8<br />
